Attachment 9- Lighting Impact Assessment

7 EVALUATION OF SITE LIGHTING PERFORMANCE

Section 7 provides an overview of evaluations of the site lighting system.
    1.1. Vertical illuminance Levels
Analysis of resultant vertical illumination in the direction of the analysis site was undertaken by AGI32
version 20.11 at the site boundary line in all directions. No value exceeded the required 25 lux initial was
measured. COMPLIANT
     1.2. Threshold Increment
Threshold Increment has been evaluated using computer modelling with AGI32 version 20.11 software.
All surrounding and internal roads where analysis as per the method outlines in AS/NZS4282-2019 at an
adaptation level of 5 applied. COMPLIANT
    1.3. Sky glow Upward Light Ratio
Calculation of the lighting model and IES formatted photometric file provided shows a compliant level of
0.00% with all luminaires installed as per STK01239-E01A. COMPLIANT
    1.4. Luminous Intensity
Analysis of resultant luminous intensity in the direction of the analysis site was undertaken by AGI32
version 20.11 at the site boundary line in all directions. No value exceeded the required 2,500 cd initial.
COMPLIANT
     7.5. Signage
No signage plans have been established for this site. We have drawn from the relevant standards, limits
to be placed on the illumination of signage to ensure compliance. All internally and externally illuminated
signage must be limited to 350 cd/m² (full white sign) and not include any dynamic images with a dwell
time less than 10 seconds with a luminance change of no more than 30%. All externally illuminated
signage must be lit from above. COMPLIANT when installed as per section 7.5.



8. CERTIFICATION

The proposed external lighting is compliant with all relevant standards, having been installed as per the
design and light control systems in place refer STK01239-E01A.
